I'd definately say don't go with panaflos on the 60mm.. I have two diferent models, and they are both whiney ass hell, and don't realy have great CFM.
I have a 60mm L1A , and a couple FBM06F12H (not sure if it's an actual H1A , they have 11 fins and are VERY whiney)
I though I'd go with all L1As for the wifes intel setup, but these are just way too loud.
